At present day world researchers are mainly focusing on the different source of fossil fuels instead of petroleum products. Normally, peoples receive biofuels from various renewable sources, example vegetable oils, agricultural wastes, sugar canes and biomass. The sources are attracted for their effect on the air from atmosphere which is maximum carbon-neutral and they are minimum toxic in the common...
Depend on the preliminary experiments, salt addition was carried out to enhance the stability of emulsions which produced via bio-oil and diesel emulsification. The presented work was focused on the effect of NaCl, a representative of salt, addition on the stability, surface tension and kinetic viscosity of emulsions. It was found that with the addition of NaCl, the emulsion stability was improved...
The world's energy consumption is estimated to be 3.36 × 1020 J per annum and is projected to increase to up to 6.3 × 1020 J in the year 2050. Due to the concern on environmental problems caused by the use of those fossil fuels, considerable attention has been given to biodiesel production as an alternative to petrodiesel. Biodiesel is advised for use as an alternative fuel for conventional petroleum-based...
The world is entering a period of declining non-renewable energy resources popularly known as “Peak Oil”. Climate change is therefore more than a problem with a feasible solution based either in science or markets on which we are likely to reach rapid consensus. Since the mid-20th century it has projected continuation. Earth is already showing many signs of worldwide climate change. One of the greatest...
Up to now the direct use of crude bio-oil as transportation fuel has been an impossible goal due to the thermal instability and some other drawbacks of bio-oil. In this paper, we use a simple method to accomplish the goal. Bio-oil and bio-diesel are potential renewable and carbon-neutral alternative to fossil fuel. We mix bio-oil and bio-diesel to get the emulsion using octanol as the emulsifier....
High consumption of chicken in Indonesia leads to a considerable amount of chicken skin as a waste. The utilization of this chicken skins as possible biodiesel feedstock was therefore investigated. The transestrification between this chicken fats and methanol was conducted using calcium oxide as solid catalyst. The variables affecting the yield of biodiesel during transesterification, such molar ratio...
The present paper will give an introduction to the work within the Cluster of Excellence (CoE) "Tailor-Made Fuels from Biomass (TMFB)", funded by the German research foundation to research on fuels from biomass for the next generation. The fluid properties of these new fuels differ a lot from conventional fuels. The paper will show the approach for finding technical solutions to deal with...
The object of this work is to reduce carbon dioxide emission and produce renewable liquid fuel (bio-oil) from locally produced rice husk by pyrolysis in a discontinuity feeding and fluidized bed reactor. The experiments are carried on at different temperatures ranging from 723 K to 923K. At 773K, the yields of bio-oil, solid and non-condensable are 53.8wt%N 19.1 wt% and 27.1wt%, respectively based...
